Survey of baked goods for propionic acid and propionates
Food Additives and Contaminants, 1996One hundred and thirty samples comprising bread (64), hamburger buns (33), pittas (16), cakes (9) and Christmas puddings (8) from various retail outlets in the UK, have been analysed for the preservative propionic acid. Only one sample of bread, two samples of hamburger buns and three samples of pitta contained propionic acid in excess of 1000 mg/kg ...

Measurement of propionate turnover in vivo using sodium [2H5]propionate and sodium [13C]propionate
Clinica Chimica Acta, 1989The outcome for children with inherited disorders of propionate metabolism is poor. To facilitate development of improved treatment in these conditions, we described techniques for the estimation of the rate of production and removal of propionate in vivo.

The pathway of propionate oxidation
Biochimica et Biophysica Acta, 1953Abstract 1. 1. The oxidation of labelled propionate in the presence of large pools of unlabelled l -lactate, d -lactate and pyruvate gives rise to the appearance of label in these pools. The appearance of label suggests that the compounds mentioned are in equilibrium with the actual intermediates.

Cardiomyopathy in propionic acidaemia
European Journal of Pediatrics, 1993Following the death of a patient with propionic acidaemia with a cardiomyopathy we reviewed 19 patients with the same disorder for evidence of cardiomyopathy. Six patients were found to meet the diagnostic criteria. Three patients died and in the other three the cardiac disease resolved completely.

Methylmalonic and propionic aciduria
American Journal of Medical Genetics Part C: Seminars in Medical Genetics, 2006AbstractMethylmalonic and propionic aciduria (PA) are the most frequent forms of branched‐chain organic acidurias. These autosomal recessive disorders result from deficient activity of methylmalonyl‐CoA mutase and propionyl‐CoA carboxylase, respectively.

The Neuropathology of Propionic Acidemia
Developmental Medicine & Child Neurology, 1983SUMMARYThe neuropathology in two biochemically documented cases of propionic acidemia is presented. While spongiform changes in white matter were seen in the infant who died at 12 days, no such changes were evident in an older patient who died at age 23 months.

The Reaction Rates of Propionic and Acetic Propionic Anhydrides
The Journal of Chemical Physics, 1936The infrared absorption spectra of mixtures of water and acetic propionic and of propionic anhydrides have been measured in the region from 5μ to 6.4μ. The intensity of the bands was found to decrease with time. By using the relative intensity of the anhydride band the reaction rate was calculated for three concentrations.
